This complex behavior is realized by miniature brains of ~1 million neurons. The use of simple recurrent neural networks (RNNs) to obtain answers to general questions is illustrated. For example, it has been shown a small RNS is able to pass delayed matching to sample (DMTS) test, forming an individual dynamic representation of the received stimulus, allowing decoding by a special external neural detector.. It has been demonstrated in the reflexive game “even-odd”, the RNS has a huge advantage over a multi-layered neural network, with the same and a larger number of neurons – reflection defeats regression. It was found that the asymmetry of outcomes in the odd-even game, which was explained by various causes, including psychological ones – “it’s easier to catch up than to run away”, is reproduced in the game of two RNNs. Obviously, there are no psychological causes here and the advantage of the player playing for “even” is explained by the more complex strategy of the “odd” player – he needs to predict the opponent’s move and choose the opposite one.

The functioning of a subject in a changing environment is most effective from the point of view of survival if the subject can form, maintain and use internal representations of the external world for decision-making. These representations are also called reflection in a broad sense. Using it, one can win in reflexive games since an internal representation of the enemy allows predicting their future moves. The goal is to assess the reflexive potential of heuristic model objects – artificial neural networks (...) – in the reflexive games “Even-Odd” (or “Matching pennies”) and “Rock-Paper-Scissors”. We used homogeneous fully connected neural networks of small sizes (from 8 to 45 neurons). Games were played between neural networks with different configurations and parameters (size, step size for modifying weight coefficients). A set of reflexivity criteria is presented, corresponding to different levels of consideration: neuronal, behavioral, formal. The transitivity of formal success in the game is shown. The most successful configurations, however, may not meet other criteria of reflexivity. We hypothesize that the best compliance with the criteria and, as a consequence, universal success in reflection tasks is achievable for heterogeneous configurations with a structure in which the formation of hierarchical systems of attractors is possible.

Let Mn♯ denote the minimal active iterable extender model which has n Woodin cardinals and contains all reals, if it exists, in which case we denote by Mn the class-sized model obtained by iterating the topmost measure of Mn class-many times. We characterize the sets of reals which are Σ1-definable from R over Mn, under the assumption that projective games on reals are determined:1. for even n, Σ1Mn=⅁RΠn+11;2. for odd n, Σ1Mn=⅁RΣn+11.This generalizes a theorem of Martin and Steel for (...) L, that is, the case n=0. As consequences of the proof, we see that determinacy of all projective games with moves in R is equivalent to the statement that Mn♯ exists for all n∈N, and that determinacy of all projective games of length ω2 with moves in N is equivalent to the statement that Mn♯ exists and satisfies AD for all n∈N.

This book presents not only the mathematical concept of probability, but also its philosophical aspects, the relativity of probability and its applications and even the psychology of probability. All explanations are made in a comprehensible manner and are supported with suggestive examples from nature and daily life, and even with challenging math paradoxes.

The authors attempt to speculatively reconstruct the concept of the “So­viet computer game”. They propose to consider gaming practices associ­ated with computers as a derivative of the accepted ideological guidelines that accompany the Soviet project of machine modernization. Within this framework, the concept of the Soviet computer game appears as an unre­alized historical alternative to the normative game design that has devel­oped in countries with market economies. Despite the industry — or the electronic entertainment market — not (...) having had the time to be properly established in the USSR, there were a number of discursive attitudes re­garding the game as such, and the gaming function of computing devices in particular. Even early Soviet pedagogical theories assumed that “playing like a Soviet” involves performing activities structurally similar to labor, where the player becomes part of production. Later, cybernetic discourse, through game theory, indicated the possibility of formalizing any prag­matic activity as a game model; with the advancement of programming, the pragmatics of digital gaming as a way of educating and solving utili­tarian tasks was developed. Based on the memoir archive of Soviet cyber­netics, and publications in the late-Soviet press, the authors demonstrate that the Soviet computer game was not seen an entertainment product, but a representative model for solving problems in an algorithmic form. Thus, the article is not about specific games that could be called Soviet, but about the logic that guided and set the tone for the interpretation of certain computer-game phenomena in the USSR.

Information communication technology is spreading fast and wide. Driven by convenience, it enables people to undertake personal tasks and make decisions more easily and efficiently. Convenience enjoys an air of liberation as well as self-expression affecting all areas of life. The industry for children's toys is a major economic market becoming ever more tech-related and drawn into the battle for convenience. Like any other tech-related industry, this battle is about industry dominance and, currently, that involves networked toys. Networked toys aim (...) to enhance convenience for children and parents alike. Increasingly difficult to resist, these convenient networked devices are also a societal game changer. Neatly nestled in a lacuna juris and surrounded by a lack of clinical evidence, networked toys raise complex ethical issues concerning human development. This article lays bare the regulatory nexus for networked toys and invites ethical thinking to fill the gap to ensure sufficient protection for all human developmental stages. Networked toys not only affect but also might interfere with child development. Therefore, the article initially summarises the four key psychological stages through which the neurological development of the human brain processes. Each of these stages involves vital windows for human development in cognitive, emotional and social dimensions. Missing any of these developmental windows changes an individual human for life. The article then takes a look at the two main legal frameworks protecting the stages of human development which are applicable to networked toys: First, the examination of the human rights framework with its major segments emanating from the fundamental rights to privacy for family and home, to a child's education as well as to personal data reveals the use of current networked toys as a shielded part of parenting which tends to be at odds with privacy and data protection requirements. Second, the product liability framework for toy manufacturers requires evidence-based causality for putting a child's safety at risk. Unfortunately, these legal frameworks fail to offer sufficient protection of the human developmental stages. There is a lacuna juris. Although networked toys involve the risk of negatively impacting human development in every dimension, clinical psychological studies are impossible to acquire as court evidence for product liability because they take too long to provide reliable data while exposing several generations of children to the examined risk in the process. Meanwhile the temptation of convenience continues to drive the industry and consumers of networked toys and devices, which are already impacting children of all age groups. Accepting this phenomenon as an element of cognitive dissonance in society and in science falls far short of an appropriate ethical balance. The need for creating such an ethical balance concerning networked toys is all the more imperative because even if the networked toy industry managed to eliminate all psychological risks for human development and every legal conflict with privacy and security, significant ethical and societal risks of networked toys remain due to inevitable technological bias. Against these mounting changes, it is suggested that only an ethical approach of interdisciplinary research and learning seems most promising to develop an appropriate equilibrium between the complex challenges posed by networked toys and the societal values at stake.

David Lewis (1969) introduced sender-receiver games as a way of investigating how meaningful language might evolve from initially random signals. In this report I investigate the conditions under which Lewis signaling games evolve to perfect signaling systems under various learning dynamics. While the 2-state/2- term Lewis signaling game with basic urn learning always approaches a signaling system, I will show that with more than two states suboptimal pooling equilibria can evolve. Inhomogeneous state distributions increase the likelihood of pooling equilibria, (...) but learning strategies with negative reinforcement or certain sorts of mutation can decrease the likelihood of, and even eliminate, pooling equilibria. Both Moran and APR learning strategies (Bereby-Meyer and Erev 1998) are shown to promote successful convergence to signaling systems. A model is presented that illustrates how a language that codes state-act pairs in an order-based grammar might evolve in the context of a Lewis signaling game. The terms, grammar, and the corresponding partitions of the state space co-evolve to generate a language whose structure appears to reflect canonical natural kinds. The evolution of these apparent natural kinds, however, is entirely in service of the rewards that accompany successful distinctions between the sender and receiver. Any metaphysics grounded on the structure of a natural language that evolved in this way would track arbitrary, but pragmatically useful distinctions. (shrink)

We consider two scenarios of the Hotelling–Downs model of spatial competition. This setting has typically been explored using pure Nash equilibrium, but this paper uses point rationalizability (Bernheim, Econometrica J Economet Soc 52(4):1007–1028, 1984) instead. Pure Nash equilibrium imposes a correct beliefs assumption, which may rule out perfectly reasonable choices in a game. Point rationalizability does not have this correct beliefs assumption, which makes this solution concept more natural and permissive. The first scenario is the original Hotelling–Downs model with (...) an arbitrary number of agents. Eaton and Lipsey (Rev Econ Stud 42(1):27–49, 1975) used pure Nash equilibrium as their solution concept for this setting. They showed that with three agents, there does not exist a pure Nash equilibrium. We characterize the set of point rationalizable choices for any number of agents and show that as the number of agents increases, the set of point rationalizable choices increases as well. In the second scenario, agents have limited attraction intervals (Feldman et al. Variations on the Hotelling–Downs model. In: Thirtieth AAAI Conference on Artificial Intelligence, pp 496–501, 2016). We show that the set of point rationalizable choices does not depend on the number of agents, apart from this number being odd or even. Furthermore, the set of point rationalizable choices shrinks as the attraction interval increases. (shrink)

Twenty years ago in "Turing's Two Tests for Intelligence" I distinguished two distinct tests to be found in Alan Turing's 1950 paper "Computing Machinery and Intelligence": one by then very well-known, the other neglected. I also explained the significance of the neglected test. This paper revisits some of the points in that paper and explains why they are even more relevant today. It also discusses the value of tests for machine intelligence based on games humans play, giving an analysis (...) of some twentieth century TV game shows and how they relate to the tests for machine intelligence in Turing's paper and in some other tests for machine intelligence that have been proposed since. Their value in distinguishing between 'wise' and simply ‘clever’ AI is discussed. (shrink)

The purpose of this article is to propose a method for analyzing the ideo­logical content of video games while taking into account the agency of the players. The interactivity of video games as a medium has been attracting the attention of researchers for many years, raising, in particular, the ques­tion of how this unique property serves to broadcast certain ideologies. The ability of games to make ideological statements was discussed by Bogost, Frasca, Aarseth, and many other pioneers of game (...) studies. Video games were analyzed both in the context of older media forms that promoted certain ideas through plots, visuals, and other traditional means, and as unique types of objects that can make statements through rules. I aim to introduce the player — as a subject who is able to transform and conceptual­ize the game based on their own cultural background — to this discussion. Using James Gibson’s theory of affordances, I want to acknowledge the player’s freedom of interpretation, the potential to assign one or another ideology to the game in each playthrough. On the one hand, the player acts as a consumer of content; on the other hand, they are a co-author who will use the tools offered by the video game to produce their own state­ments, to be interpreted independently. This leaves the final decision about the ideology of the game to the consumer; thus, game studies need an ap­proach that allows the analysis of the ideological content of specific games. It is especially important in the light of more and more games prioritizing player freedom and not providing any clear plot or even victory conditions. Of course, research can still proclaim, and rightfully so, that the specific rules in such games bear traces of certain ideological systems — capitalism or secularism, for example. But individual players could undermine such interpretations both at the level of reading the game as a “text”, and at the level of interactive actions inspired by those readings. (shrink)

I suggest an account of desuetudo in game-theoretic terms. I argue that there is an asymmetry with consuetudo, because consuetudo cannot be fully captured by a game-theoretic analysis, while desuetudo, properly understood as a dynamic, diachronic process, can. A norm (not necessarily a consuetudo) ceases to exist because there’s no need anymore, in an interactive situation, to foster certain equilibria, even though the same norm which is going in desuetudo might not have emerged as a consuetudo. (...) While this kind of norm dynamics cannot explain all kinds of consuetudines, it can explain desuetudo, understood as a dynamic process ending with normative indifference, from a state which was normatively relevant. In this game-theoretic account the dynamicity is captured by the repeated occurence of the game, while desuetudo is the opposite process, in terms of normativity, with which a norm emerges (regardless of the fact whether the initial norm was a consuetudo or posited).

Recent empirical research demonstrates that cross-holding engenders significant anti-competitive effect even though it confers no decisive influence on the target firm. This research has obtained wide attention, which leads to both calls for and actual changes in antitrust policy. However, the effects of cross-holding on competition are not well established. This paper examines the collusive effect of cross-holding with asymmetry in cost functions across firms in an infinitely repeated Cournot duopoly game. The two firms have a different (...) share of capital that affects marginal costs. We find that cross-holding facilitates collusion when a small firm (i.e., a firm with a small capital capacity) increases its passive ownership in a big firm (i.e., a firm with a large capital capacity), and the size of initial ownership is relatively small. Unexpectedly, collusion becomes more difficult to be sustained when a big firm increases ownership in a small firm, or when a small firm increases ownership in a big firm but the initial ownership is relatively large. Our result that cross-holding may either facilitate or hinder collusion, under certain circumstances, generates important implications for antitrust policy. (shrink)

In the basic model of Condorcet’s jury theorem and in the literature that follows, an odd-numbered group of voters is assumed so that the simple majority rule can be used. We show that this assumption is not necessary either in Condorcet’s basic model or in the general framework of dichotomous choice. We first apply simple majority rule to an even-numbered homogeneous fixed-size committee. We then provide a justification for using simple majority rule for an even-numbered heterogeneous fixed-size committee (...) when the competence structure of the committee members is not common knowledge.

A cornerstone of game theory is backward induction, whereby players reason backward from the end of a game in extensive form to the beginning in order to determine what choices are rational at each stage of play. Truels, or three-person duels, are used to illustrate how the outcome can depend on (1) the evenness/oddness of the number of rounds (the parity problem) and (2) uncertainty about the endpoint of the game (the uncertainty problem). Since there is no (...) known endpoint in the latter case, an extension of the idea of backward induction is used to determine the possible outcomes. The parity problem highlights the lack of robustness of backward induction, but it poses no conflict between foundational principles. On the other hand, two conflicting views of the future underlie the uncertainty problem, depending on whether the number of rounds is bounded (the players invariably shoot from the start) or unbounded (they may all cooperate and never shoot, despite the fact that the truel will end with certainty and therefore be effectively bounded). Some real-life examples, in which destructive behavior sometimes occurred and sometimes did not, are used to illustrate these differences, and some ethical implications of the analysis are discussed.

Over the past two decades, gamblers have begun taking mathematics into account more seriously than ever before. While probability theory is the only rigorous theory modeling the uncertainty, even though in idealized conditions, numerical probabilities are viewed not only as mere mathematical information, but also as a decision-making criterion, especially in gambling. This book presents the mathematics underlying the major games of chance and provides a precise account of the odds associated with all gaming events. It begins by explaining (...) in simple terms the meaning of the concept of probability for the layman and goes on to become an enlightening journey through the mathematics of chance, randomness and risk. It then continues with the basics of discrete probability, combinatorics and counting arguments for those interested in the supporting mathematics. These mathematic sections may be skipped by readers who do not have a minimal background in mathematics; these readers can skip directly to the Guide to Numerical Results to pick the odds and recommendations they need for the desired gaming situation. Doing so is possible due to the organization of that chapter, in which the results are listed at the end of each section, mostly in the form of tables. The chapter titled The Mathematics of Games of Chance presents these games not only as a good application field for probability theory, but also in terms of human actions where probability-based strategies can be tried to achieve favorable results. Through suggestive examples, the reader can see what are the experiments, events and probability fields in games of chance and how probability calculus works there. The main portion of this work is a collection of probability results for each type of game. Each game s section is packed with formulas and tables. Each section also contains a description of the game, a classification of the gaming events and the applicable probability calculations. The primary goal of this work is to allow the reader to quickly find the odds for a specific gaming situation, in order to improve his or her betting/gaming decisions. Every type of gaming event is tabulated in a logical, consistent and comprehensive manner. The complete methodology and complete or partial calculations are shown to teach players how to calculate probability for any situation, for every stage of the game for any game. Here, readers can find the real odds, returned by precise mathematical formulas and not by partial simulations that most software uses. Collections of odds are presented, as well as strategic recommendations based on those odds, where necessary, for each type of gaming situation. The book contains much new and original material that has not been published previously and provides great coverage of probabilities for the following games of chance: Dice, Slots, Roulette, Baccarat, Blackjack, Texas Hold em Poker, Lottery and Sport Bets. Most of games of chance are predisposed to probability-based decisions. This is why the approach is not an exclusively statistical one, but analytical: every gaming event is taken as an individual applied probability problem to solve. A special chapter defines the probability-based strategy and mathematically shows why such strategy is theoretically optimal.". (shrink)

Most of the images evoked by the term shamanism are derived from the soul's field of experience. These images run the gamut of possibilities, from a disconcerting exoticism to the most intimate familiarity. Sometimes the shaman's role is limited to that of pathetic hero, struggling in solitude against hostile nature; sometimes he becomes the rudimentary model of the mystic or even of the psychiatrist of contemporary societies. These images, however, without being completely false, wrongly reduce the shamanic phenomenon to (...) the shaman's personality and limit his field of action to the individual psyche. This limitation hardly does justice to the realities of shamanistic societies. What is missing in the shaman-centered view is the collective's slumbering velleity of itself entering into shamanic experience. Each cure becomes an occasion for collective renewal and joy. The shaman's activities in séance, it is believed, are an expression of the direct contact he has established with the spirits and of his power over them; his duties are the realization of a ritual act carried out at the behest of the community.

David Benatar, in Better Never to Have Been , sets out two arguments in support of the view that coming into existence is always a net harm. Remarkably, the first argument seems to imply that coming into existence would be a net harm even if the only bad we experienced in our lives were a ‘single pin-prick’. This argument hinges on a purported asymmetry: that whereas the absence of pains in non-existence is good, the absence of pleasures in (...) non-existence is not bad (rather than bad ). It also hinges on the non-badness at issue here being relative (no worse than the presence of pleasures in existence) rather than intrinsic (value neutral). To establish the crucial claim that the non-badness of absent pleasures in non-existence is relative rather than intrinsic, Benatar constructs an analogy involving two people, Sick and Healthy. In this paper, I show the inaptness of the analogy and also provide positive reason to doubt the soundness of the argument as it stands. What emerges from this critical analysis of the analogy is a plausible theory of value at odds with Benatar’s argument as a whole. (shrink)

In a previous paper, we argued that death's badness consists in the deprivation of pleasurable experiences which one would have had, had one died later rather than at the time of one's actual death. Thus, we argued that death can be a bad thing for the individual who dies, even if it is an experiential blank. But there is a pressing objection to this view, for if the view is correct, then it seems that it should also be the (...) case that it is a bad thing for a person that he is born when he actually is born, rather than earlier. That is, if the deprivation account is the correct account of death's badness, then it appears that one should have symmetric attitudes to prenatal and posthumous nonexistence. But clearly we do not in general have symmetric attitudes toward the period before our birth and the period after our death; in general, we do not think of our late births as a bad thing, but we can indeed consider our early deaths as bad for us. Thus, it appears that there is a problem for the deprivation account of death's badness. (shrink)

Abortion has become such an indispensable part of contemporary experience that even Christians sometimes find it difficult to oppose. Since taking the life in utero has ceased to be regarded as a grave sin and is not always recognized as an unmitigated evil, those who wish to remain faithful to the Word of God struggle to find ways of speaking against killing of the unborn. Some of them, like Erika Bachiochi, seek to beat modern culture at its own (...) class='Hi'>game, by representing Catholic teaching on human sexuality as a “right kind” of feminism. However, in her appeal to secular rationality, foregoing the metaphysical commitments of faith and replacing them with the consequentialist reasoning and data from scientific research, she thereby renders her alternative unviable and un-Christian. In response to this failure, I would like to present some Orthodox Christian considerations pointing toward a more wholesome and consistent way forward. (shrink)

The paper reviews Balashov’s Asymmetry Thesis concerning co-existing (point-sized) enduring objects, on the one hand, and perduring ones, on the other. In this regard, it becomes crucial to investigate whether, at a given spacetime point p, it is located only the respective temporal part of a perdur- ing whole, or that whole as well. Two alternatives ought to be distinguished and, then, I will argue as follows: If the perduring whole is located where its parts are, the original (...) class='Hi'>asymmetry- thesis has to be rejected. If, however, the perduring whole is not located where its parts are, the spatiotemporal locations of the parts can no longer be used to ground the co-existence relation. But, with the modified co-existence relation the asymmetry between perdurantism and endurantism turns out to be even much stronger than it has been assumed. (shrink)

Intimate partner violence (IPV) is a major health and human rights problem globally. However, empirical findings on the predictors of IPV cross-culturally are highly inconsistent, and the theory of IPV is underdeveloped. We propose a new analytical framework based on cooperative game theory in which IPV is a function of the power relations of the dyadic relationship, not simply the actors involved. Using data from the 2005 Colombian Demographic and Health Survey, we test the hypothesis that IPV is predicted (...) by large asymmetries in dyadic power using a hierarchical generalized linear model. Results suggest that education, urban residence, age at sexual debut, whether the woman has other sexual partners, and the age difference between spouses have strong effects on the log-odds of a woman experiencing IPV. Cooperative game theory and social network analysis offer a general approach to the problem of intimate partner interactions which can be applied broadly cross-culturally. (shrink)

We propose a new game to strategically justify the constrained equal awards rule in claims problems. Our game is “procedurally fair” and “multilateral”. In addition, even if claimants cannot reach an agreement in any period, they can renegotiate in the next period. We show that, for each claims problem, the awards vector chosen by the constrained equal awards rule achieved at period 1 is the unique subgame perfect equilibrium outcome of the game.

In many jurisdictions, adolescents acquire the right to consent to treatment; but in some cases their refusals – e.g. of life-saving treatment – may not be respected. This asymmetry of adolescent consent and refusal seems puzzling, even incoherent. The aim here is to offer an original explanation, and a justification, of this asymmetry. Rather than trying to explain the asymmetry in terms of a variable standard of competence – where the adolescent is competent to consent to, (...) but not refuse, certain interventions – the account offered here focuses more closely on the normative power to render actions permissible. Where normative powers are shared they can readily give rise to an asymmetry between consent and refusal. We then turn to why it is justifiable that normative powers be shared in adolescence. Transitional paternalism holds that the acquisition of normative powers by competent adolescents should not be an instant one, achieved in a single step, but that there should be a transitional period where paternalistic protection is rolled back, but not entirely withdrawn until a later date. Transitional paternalism could be implemented without generating the asymmetry between consent and refusal but, it is argued, the asymmetric version of transitional paternalism is to be preferred insofar as it offers a greater respect for the adolescent's decisions than the symmetrical alternative.

The belief that damaging an object may harm the individual to which the object relates is common among adults. We explored whether arousal following the destruction of a photograph of a loved partner is greater than that following the destruction of a photograph of a stranger, and whether this response is greater than when a photograph representing a non-person sentimental attachment is destroyed, using a measure of skin conductance response. Long-term supporters of a football team, who were also in a (...) long-term relationship, showed increased arousal when asked to destroy a photograph of their partner, but not a photograph of their team, even though both elicited equivalent ratings of emotional attachment. This may be because football teams are conceptualized differently from individuals. Future studies should address whether destruction of symbols that represent the enduring nature of the team elicit more emotional distress than photograph. (shrink)

Let it be allowed, though virtue or moral rectitude does indeed consist in affection to and pursuit of what is right and good, as such; yet, that when we sit down in a cool hour, we can neither justify to ourselves this or any other pursuit, till we are convinced that it will be for our happiness, or at least not contrary to it.—Butler, Sermon XIThere are a number of different grounds on which philosophers have argued that the question “Should (...) I be moral?” is unintelligible or at least somewhat odd. Some evidently are unable to understand ‘should’ in any other way than ‘morally ought’, with the consequence that the question can admit of no answer but the affirmative. Others, influenced by the later Wittgenstein, hold that, although ‘should ’-questions have a role within the moral language game, the ‘should’ in the question above has no real function, it is like a ‘machine idling,’ and we can attribute no real sense to it. Now I consider neither of these arguments to be successful or even very plausible, but I do wish to consider a further argument which is logically independent of the above and which appears, initially at least, to be quite plausible.

In spite of its infinite expectation value, the St. Petersburg game is not only a gamble without supply in the real world, but also one without demand at apparently very reasonable asking prices. We offer a rationalizing explanation of why the St. Petersburg bargain is unattractive on both sides (to both house and player) in the mid-range of prices (finite but upwards of about $4). Our analysis – featuring (1) the already-established fact that the average of finite ensembles of (...) the St. Petersburg game grows with ensemble size but is unbounded, and (2) our own simulation data showing that the debt-to-entry fee ratio rises exponentially – explains why both house and player are quite rational in abstaining from the St. Petersburg game. The house will be unavoidably (and intentionally) exposed to very large ensembles (with very high averages, and so very costly to them), while contrariwise even the well-heeled player is not sufficiently capitalized (as our simulation data reveals) to be able to capture the potential gains from large-ensemble play. (Smaller ensembles, meanwhile, enjoy low means, as others have shown, and so are not worth paying more than $4 to play, even if a merchant were to offer them at such low prices per trial.) Both sides are consequently rational in abstaining from entry into the St. Petersburg market in the mid-range of asking prices. We utilize the concept of capitalization vis-à-vis a gamble to make this case. Classical analyses of this question have paid insufficient attention to the question of the propriety of using expected values to assess the St. Petersburg gamble. And extant analyses have not noted the average-maximum-debt-before-breaking-even figures, and so are incomplete. (shrink)

The paper defends a compatibilist solution to the problem of the relationship between divine and human freedom. It is argued that the asymmetry of ability constituted by our ability to foreknowledge influence the future and our inability to control the past results from the asymmetry of openness between fixed past and open future interpreted in terms of the asymmetry of counterfactual dependence. Therefore, if the asymmetry of openness is not true of some types of facts, then (...) we may be able to control them even if they are facts about the past. It turns out that widely shared accounts of the nature and source of God’s foreknowledge entail that the asymmetry of openness does not apply to God’s past beliefs about future contingencies. Thus, it is unjustified to claim that we are unable to now do anything such that, if we were to do it, God’s past beliefs would have been different. (shrink)

Game theory based on rational choice is compared with game theory based on evolutionary, or other adaptive, dynamics. The Nash equilibrium concept has a central role to play in both theories, even though one makes extremely strong assumptions about cognitive capacities and common knowledge of the players, and the other does not. Nevertheless, there are also important differences between the two theories. These differences are illustrated in a number of games that model types of interaction that are (...) key ingredients for any theory of the social contract. (shrink)

Despite the fact that US presidential candidates commonly position themselves as Washington outsiders, this broadly populist positioning has thus far been significantly undertheorized. On the one hand, scholars of political representation have explored how politicians connect with political audiences; on the other, populism research has focused on the construction, mainstreaming and appeal of populist performances. A detailed theorization of the paradoxical performative operation by which self-styled political outsiders come to be more effective in connecting with political audiences than accomplished politicians (...) has yet to be undertaken. This article explores the performativity of outsider positioning, paying particular attention to its effect on perceptions of legitimacy. The article investigates legitimacy as a complex and paradoxical performative phenomenon that involves multiple competing sources of agency. The case is made that, by discouraging the perception of the political system as a unified whole, populist-style performances by mainstream politicians undermine institutional legitimacy. In a way that is at odds at odds with the cooperative demands inherent in the US federal government, these performances encourage the perception that the self-styled outsider is engaged in a strictly competitive zero-sum game with the institutional structure and its representatives.

The skewness of a distribution, a poorly-defined term, is conventionally deemed to be invariant under linear transformations. A comparison is made of three criteria of it: the sign of odd central moments; the several relationships of the mean, the median and the mode; and asymmetry proper which is the set of ratios of the probability densities of all pairs of points equidistant above and below some arbitrary point, usually the principal mode. Some useful general relationships are discussed. The skeness (...) of convolutions is briefly discussed. A class of distributions is identified for which the skewness of the minimum ofk competing processes is independent ofk. It has importance in the parametric study of survivorship. (shrink)

In signaling games, a sender has private access to a state of affairs and uses a signal to inform a receiver about that state. If no common association of signals and states is initially available, sender and receiver must coordinate to develop one. How do players divide coordination labor? We show experimentally that, if players switch roles at each communication round, coordination labor is shared. However, in games with fixed roles, coordination labor is divided: Receivers adjust their mappings more frequently, (...) whereas senders maintain the initial code, which is transmitted to receivers and becomes the common code. In a series of computer simulations, player and role asymmetry as observed experimentally were accounted for by a model in which the receiver in the first signaling round has a higher chance of adjusting its code than its partner. From this basic division of labor among players, certain properties of role asymmetry, in particular correlations with game complexity, are seen to follow. (shrink)

The mechanisms responsible for the fine tuning of development, where the wildtype phenotype is reproduced with high fidelity, are not well understood. The difficulty in approaching this problem is the identification of mutant phenotypes indicative of a defect in these fine‐tuning control mechanisms. Evolutionary biologists have used asymmetry as a measure of developmental homeostasis. The rationale for this was that, since the same genome controls the development of the left and right sides of a bilaterally symmetrical organism, departures from (...) symmetry can be used to measure genetic or environmental perturbations. This paper examines the relationship between asymmtry and resistance to organophosphorous insecticides in the Australian sheep blowfly, Lucilia cuprina. A resistance gene, Rop‐1, which encodes a carboxylesterase enzyme, also confers a significant increase in asymmetry. Continued exposure of resistant populations to insecticide has selected a dominant suppressor of the asymmetry phenotype. Genetic evidence indicates that the modifier is the L. cuprina Notch homologue. (shrink)

The aim of the series of the three articles entitled “Name game…” is to present the historical information about nomenclature history of every known chemical element. The process of naming each chemical element is analyzed, with particular emphasis on the first publication with a given name. It turned out that in many cases this information is not obvious and unambiguous, and the published data are even contradictory. In a few cases, the names of the elements were changed (...) class='Hi'>even several times. Moreover, even when the author of a given element name is known, it is sometimes not entirely clear in which publication he/she first used it. Therefore, the series of three articles are an attempt to sort out the issue of first publishing of the names of all 118 chemical elements known so far, based on original source texts, available thanks to the digitization of a number of collections of scientific literature. The articles are divided according to the time of discoveries: (1) research till the end of the 18th century, (2) discoveries in the 19th century, (3) discoveries and syntheses of elements in the 20th and 21st centuries. This particular article presents the history of naming of the first 37 elements: known from antiquity, discovered in nature and named in 17th and 18th century. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Missing the Cross?Types of the Passion in Early Christian ArtS. Mark Heim (bio)René Girard has frequently contended that the core of his best known theories is already contained in the Bible, that in the end he is "only a kind of exegete" (Girard and Treguer 1994, 196). To those who object that the Bible had to wait two thousand years to be read as he reads it, he protests (...) that this is a gross exaggeration: "three quarters of what I say can be found in Saint Augustine" (196). In the introduction to I See Satan Fall like Lightning, Girard puts it like this:The Passion accounts reveal a phenomenon that unbeknownst to us generates all human cultures and still warps our human vision in favor of all sorts of exclusions and scapegoating. If this analysis is true, the explanatory power of Jesus's death is much greater than we realize, and Paul's exalted idea of the cross as the source of all knowledge is anthropologically sound.(2001, 3)In other words, Girard's insight comes only in the train of revelation. The revelation in the biblical sources was not perfectly grasped in the religious traditions that flowed from them, and was frequently betrayed through the construction of sacrificial theologies. But Girard insists that its power was in significant measure perceived and effective from the beginning. His view of the meaning of the passion cannot be correct if he is the first one to see it. So it is no minor matter to ask whether in fact early Christians saw the connection of the cross with scapegoating that is so central for Girard.One point that appears to tell against Girard's case is the absence of images of the cross and crucifixion in the first four Christian centuries. A brutal realism about this specific event is the keystone of Girard's understanding of the passion narratives. The fact that the sight is literally hidden from view throughout this formative Christian period hardly appears consistent with his claims.There is a notable early Christian work of art, the so-called Brescia Casket (see fig. 1), that sheds some important light on the general question of the [End Page 183] representation of the passion and, even more dramatically, upon its interpretation in Girardian terms. The casket indicates that the widespread use of Old Testament types as representations of Christ, and specifically as representations of his passion, may partly explain the absence of literal depiction of the crucifixion. And the particular types involved fit extremely well with Girard's outlook. This essay draws out the connection—so far unremarked—between this significant work of early Christian art and Girard's reading of the passion. Click for larger view View full resolutionFigure 1.Brescia Casket. Ivory, late fourth century.Christ's passion and death were described in stark terms in the gospels and recounted explicitly from the beginning in the church's liturgy, teaching, and preaching. On this plane, there is no question of the centrality of the cross. Yet no literal depictions of the crucifixion survive in art from the first four Christian centuries. There is no entirely satisfactory explanation of why the cross would figure so centrally in Christian faith and worship, but be visually absent. Representations of Jesus in early Christian art most often display a healer, wonderworker, or teacher. In fact, the early centuries offer an odd inversion in creed and art. Early creeds focus on Jesus's beginnings and endings, "skipping right from 'born of the Virgin Mary' to 'suffered under Pontius Pilate,' with no mention of Jesus's life and work, while the art appears to take an opposite tack" (Jensen 2000, 131–32). Perhaps the frequent Christian use [End Page 184] of images of anchors and ship's masts, or of the chi-rho sign, served as their image of the cross. Perhaps the reality the scriptures described was too gruesome to easily picture, too readily ridiculed by outsiders, or too awesome and mysterious to present directly. Perhaps, in a persecuted and at times martyred church, such a sign would be realistically terrifying to many and dangerously seductive to some.That the... (shrink)

In this paper, I defend a grammatical account of scalar implicatures. In particular, I submit new evidence in favor of the contextual blindness principle, assumed in recent versions of the grammatical account. I argue that mismatching scalar implicatures can be generated even when the restrictor of the universal quantifier in a universal alternative is contextually known to be empty. The crucial evidence consists of a hitherto unnoticed oddness asymmetry between formally analogous existential sentences with reference failure NPs. I (...) conclude that the generation of mismatching scalar implicatures does not require contextual access. (shrink)

It might surprise someone, who knew only On Liberty, to hear J. S. Mill called the father of British socialism. That would sound a careless bid for a respectable pedigree, on a par with hailing King Canute as father of the British seaside holiday. Mill is passionate there about making the individual a protected species, not to be interfered with even for his own good, unless to prevent harm to others. He is so passionate that government seems at times (...) to have no other task than to protect. The Principles of Political Economy, on the other hand, displays clear, if intermittent, socialist leanings. There too ‘there is a circle round every individual human being, which no government… ought to be permitted to overstep’. But, subject to this constraint, government is urged to do all the utilitarian good it can and some nasty worries for democratic socialists surface instructively. They centre on the social aspects of individuality and give rise to problems in what my title calls the Social Liberty Game. British socialism, with its Lib-Lab origins and tolerant respect for individual liberty, embodies a tension between the rights of each and the good of all, which makes the Principles a living part of its intellectual history.

There is widely assumed to be a fundamental epistemological asymmetry between self-knowledge and knowledge of others. They are said to be ’categorically different in kind and manner’ , and the existence of such an asymmetry is taken to be a primitive datum in accounts of the two kinds of knowledge. I argue that standard accounts of the differences between self-knowledge and knowledge of others exaggerate and misstate the asymmetry. The inferentialist challenge to the asymmetry focuses on (...) the extent to which both self-knowledge and knowledge of others are matters of inference and interpretation. In the case of self-knowledge I focus on the so-called ‘transparency method’ and on the extent to which use of this method delivers inferential self-knowledge. In the case of knowledge of others’ thoughts, I discuss the role of perception as a source of such knowledge and argue that even so-called ’perceptual’ knowledge of other minds is inferential. I contend that the difference between self-knowledge and knowledge of others is a difference in the kinds of evidence on which they are typically based. (shrink)

Social relationships are essential for humans; neglecting our social needs can reduce wellbeing or even lead to the development of more severe issues such as depression or substance dependency. Although essential, some individuals face major challenges in forming and maintaining social relationships due to the experience of social anxiety. The burden of social anxiety can be reduced through accessible assessment that leads to treatment. However, socially anxious individuals who seek help face many barriers stemming from geography, fear, or disparities (...) in access to systems of care. But recent research suggested digital behavioral markers as a way to deliver cheap and easily accessible digital assessment for social anxiety: As earlier work shows, players with social anxiety show similar behaviors in virtual worlds as in the physical world, including tending to walk farther around other avatars and standing farther away from other avatars. The characteristics of the movement behavior in-game can be harnessed for the development of digital behavioral markers for the assessment of social anxiety. In this paper, we investigate whether implicit as well as explicit digital behavioral markers, proposed by prior work, for social anxiety can be used for predicting the level of social anxiety. We show that both, explicit and implicit digital behavioral markers can be harnessed for the assessment. Our findings provide further insights about how game-based digital behavioral markers can be used for the assessment of social anxiety. (shrink)

The paper investigates the video game discourse of the Russian state media from 2011 to 2015. Critical discourse analysis serves as a methodological framework for this work, and Foucault’s power/knowledge model is used to explain the logic behind the «grotesque discourses». In the Russian press, video games are described as an instance of inculcation, provoking overintense emotions and forcing individuals to commit symbolic acts impossible from the standpoint of “normal” pedagogy. The paper problematizes the mythologization of violence in video (...) games and identifies the main tropes used to establish the connection between video games and violence (murders) as “natural” and “obvious”. Particular attention is paid to the publications of Aleksandr Minkin, a reporter at “Moskovskij Komsomolets” (“Moscow Komsomol Member”) and one of the most prominent critics of video games, as well as to the media coverage of the first school shooting in Russia (shooting at school № 263 in 2014). It is shown that video games are used in the media discourse as an explanatory principle that allows a shift from the crime to the criminal, to those acts which reveal moral depravity or psychological disorder, and those circumstances which foster criminalism. Pointing to the games helps restore the “normal” connection between social and moral qualities, explaining the crime committed by an honours student from a “good family” as being the result of the depictions of violence in video games affecting the child’s psyche. Video games are also described as a factor in shaping the “digital generation” or “generation of gamers” — odd and politically dangerous. The dangers that games create for both gamers and society in general (the non-distinction between the “real” and the “virtual”, the illusion of a “possible restart”) allow the journalists and experts to insist on strengthening measures of supervision and protection, and expanding legal and medical control.
